This is an example of the problem of CWP developers, failing to publish a changelog.
We simply don't know what was changed, at least in features, and if you have customizations, you are lost.
Seems that file now is unused, due to that config had changed to be made at database level.
Check youself, acessing the phpMyAdmin, database 'root_cwp', table 'settings', field 'named_tpl', have a identical configuration of that template.
